Described herein are compositions, kits, and methods for potent delivery to a cell of a subject. The cell can be of a particular cell type, such as a basal cell. In some cases, the cell can be a lung cell of a particular cell type. Also described herein are pharmaceutical compositions comprising a therapeutic or prophylactic agent assembled to a lipid composition. The lipid composition can comprise an ionizable cationic lipid, and a selective organ targeting lipid. The lipid composition can further comprise a phospholipid. Further described herein are high-potency intravenous dosage forms of a therapeutic or prophylactic agent formulated with a lipid composition.

Provided herein are lung forming progenitor cell therapies which do not require pre-conditioning treatments. Administration of the progenitor cells can replace or replenish populations of host-derived patch forming cells to reverse or inhibit fibrosis, promote healing, and improve lung function. Further disclosed herein are methods for monitoring fibrosis, and for determining whether a subject will be receptive to progenitor cell treatments.

Provided herein are lipid nanoparticle (LNP) compositions for use in delivering a payload to a lung cell of a subject. Also provided are a method for treating and / or preventing a lung disease, kits, pharmaceutical compositions, and other compositions and methods.

Provided are methods for delivering lipid nanoparticles (LNPs) to a lung cell of a subject suffering from or at risk for primary ciliary dyskinesia (PCD), wherein the method comprises nebulizing a liquid pharmaceutical composition to generate an aerosolized pharmaceutical composition, and administering the aerosolized pharmaceutical composition to the subject.

There are provided herein, inter alia, complexes, compositions and methods for the delivery of therapeutic, diagnostic and imaging agents, including nucleic acid, into a cell. The complexes, compositions and methods may facilitate complexation, protection, delivery and release of oligonucleotides and polyanionic cargos into lung cells and lung tissue, both in vitro and in vivo.

This invention relates to the field of traditional Chinese medicine fermentation technology, specifically a method for preparing fermented Citrus reticulata peel that improves lung function and repairs lung cells. The method involves sterilizing crude Citrus reticulata peel powder with water to create a solid-state fermentation substrate, inoculating it with a composite seed liquid prepared from a mixture of Saccharomyces cerevisiae and Lactobacillus plantarum in a specific ratio. Solid-state fermentation is carried out under strict temperature and humidity control, supplemented by regular turning operations. The fermented material is then dried at low temperature and pulverized to obtain the final product. This complex biotransformation process specifically induces the generation of CSMI Citrus reticulata peel flavonoid-glucopyranoside, which is completely absent in the original medicinal material. This newly generated active ingredient produces a strong synergistic effect with the inherent components, significantly enhancing the overall efficacy in relieving cough and phlegm, inhibiting the release of inflammatory factors in the lungs, and repairing damaged lung epithelial cells. The resulting product can be directly used in the formulation of related pharmaceutical preparations and functional foods.

This invention discloses a 3D scaffold for repairing defective lung injury, its construction method, and its applications, belonging to the field of biomedical materials and tissue engineering technology. This invention uses cationic polysaccharide chitosan and polymer γ-polyglutamic acid as raw materials, utilizing their electrostatic interaction to achieve cross-linking without cross-linking agents, and combines this with freeze-drying technology to prepare a three-dimensional spherical γ-PGA / CS composite scaffold. The above composite scaffold is combined with bone marrow stem cell exosomes (MSC-Exos) and type II alveolar epithelial cells (RLE-6TN). By loading exosomes onto the scaffold and implanting lung cells, local enrichment and targeted delivery are achieved, solving the problems of poor targeting of bone marrow stem cell exosomes and easy loss during transplantation of individual cells. This functional scaffold can accelerate lung function recovery by regulating the inflammatory microenvironment at the site of lung injury in SD rats, promoting lung cell regeneration, and reducing secondary lung tissue damage. It provides a novel implantable, minimally invasive treatment for defective lung injury-related diseases, possessing good clinical translational potential and application prospects in organ damage repair.

Described are RNAi agents, compositions that include RNAi agents, and methods for inhibition of a Receptor for Advanced Glycation End-products (AGER or RAGE) gene. The RAGE RNAi agents and RNAi agent conjugates disclosed herein inhibit the expression of an AGER gene. Pharmaceutical compositions that include one or more RAGE RNAi agents, optionally with one or more additional therapeutics, are also described. Delivery of the described RAGE RNAi agents to pulmonary cells, in vivo, provides for inhibition of AGER gene expression and a reduction in membrane RAGE activity, which can provide a therapeutic benefit to subjects, including human subjects, for the treatment of various diseases including pulmonary inflammation diseases such as severe asthma.
